[Off-Topic ?] Problem with Struts/Tomcat/Jbuilder/ ?
Hi,
I have a very strange problem here. And I don't know what is the cause of
that problem (Tomcat ? Struts ? JBuilder ? something else ?).
Here's my problem: when I run a first time my project with Jbuilder 6
(using Tomcat 4.0.1), I have practically no problem.
Then I stop the Tomcat server and try to run it again (without changing a
thing !). And suddenly, the following exception is thrown:

Hi
I also use TC4.0.1, Struts and JB6(pro) and have seen a similar problem.
To be honest I can't remember how I cured but I think it was because I had a
reference to the servlet library in the JB project props - you try looking

Also - do you get the same problem when you deploy your project as a war and

RE: [Off-Topic ?] Problem with Struts/Tomcat/Jbuilder/ ?
I have run with a similar environment and found no problems at all, so it's not a
problem with JBuilder per se, perhaps they way you have it confgiured.
I would recomend you install the latest patch for JBuilder 6 (available at the
website) and try it against an External instance of Tomcat 4 as suggested elsewhere.
The other thing to try would be to upgrade to 4.0.2 and test against that.
Sorry I cant help any more, but if you supply more info on your configuration perhaps
I can. Im certain its a config issue and not a JBuilder/Tomcat issue.
Thanks

Re: [Off-Topic ?] Problem with Struts/Tomcat/Jbuilder/ ?
Hi,
I'm not sure that I understood what you wrote. Of course, I have a
reference to the servlet library in the properties of my jbuilder project
:) Why shouldn't I have that reference (in the required libraries) ?
Sorry, if I misunderstood your reply but I'm just a newbie in the
development of Web Application.
For the rest, I tried deploying my webapp with Tomcat and I had the same
problem (!!!).
So I'd suppose, it's a Tomcat problem (or a Struts prob ?).
I also patched my Jbuilder 6.0 with the latest update available without any
improvement.
I didn't try to update my version of Tomcat. Because I first wanna be sure
it's Tomcat causing the problem and not something else...
Friendly Regards,
Slimane

Hi
I also use TC4.0.1, Struts and JB6(pro) and have seen a similar problem.
To be honest I can't remember how I cured but I think it was because I had a
reference to the servlet library in the JB project props - you try looking
there.
Also - do you get the same problem when you deploy your project as a war and
run under TC outside of JB6? - might give some clue as to where the problem
lies.

Hi,
I have a very strange problem here. And I don't know what is the cause of
that problem (Tomcat ? Struts ? JBuilder ? something else ?).
Here's my problem: when I run a first time my project with Jbuilder 6
(using Tomcat 4.0.1), I have practically no problem.
Then I stop the Tomcat server and try to run it again (without changing a
thing !). And suddenly, the following exception is thrown:
Apache Tomcat/4.0.1 - Error report!--H1{font-family :
sans-serif,Arial,Tahoma;color : white;background-color : #0086b2;}
